Summer Marginal Ice Zone: A Potential Predictor for September Arctic Sea Ice Extent

Abstract The Arctic summer marginal ice zone (MIZ) represents a growing fraction of total sea ice extent (SIE), yet its predictive performance for September Arctic sea ice remains unknown. This study reveals that summer (June–August) MIZ area fraction is an optimal predictor for...

Microfluidic-based high-throughput isolation enhances the recovery of novel strains and diversity from Arctic soil microbiome

ABSTRACT Microbial cultivation remains essential for understanding the physiology, ecology, and biotechnological potential of environmental microbes, yet conventional plate-based methods (CPM) recover only a minute fraction of the environmental microbiome. Polar regions, particul...

Vegetation-driven shifts in soil microbial communities and predicted carbon-cycling potential across soil depths in High-Arctic islands

Abstract Background Arctic ecosystems are experiencing unprecedented warming, driving vegetation expansion into previously barren areas. Although Arctic greening is expected to alter biogeochemical cycles, how vegetation cover shapes soil microbial communities and their functiona...

Year-Round High-Resolution Sea Ice Freeboard Retrieval Using ICESat-2 ATL03 Photon Data

Abstract. Arctic sea ice freeboard is critical for estimating ice thickness and characterizing surface morphology, yet it remains poorly constrained, especially during the melt season due to limitations in conventional altimetry products. The ICESat-2 ATL07 product retrieves surf...
